4.1 From the question, the normal charge of electricity excluding VAT for 0 - 50 range was 0.6340. The price including VAT in the table was calculated as

[tex]\begin{gathered} Price+VAT=\frac{0.6340\times115}{100} \\ this\text{ is because the VAT is 15\%, so add to 100\% to} \\ get\text{ 115\%, then divide by 100} \\ \frac{0.6340\times115}{100}=0.7291 \end{gathered}[/tex]

4.2

If SIzwe used 222 kWh of electricity, the range of this from the table fall under >50 - 350, and the charge for that is 1.0804
